Install Mysql5.7 on CentOS7 (decompress Version)

Install Mysql5.7 on CentOS7 (decompress Version)

#### 1. Download the installation package
Http://dev.mysql.com/downloads/mysql/#downloads
We recommend that you download the TAR package of the general installation method.

2. Check whether the library file exists. If yes, delete it.

[root@localhost Desktop]$ rpm -qa | grep mysqlmysql-libs-5.1.52-1.el6_0.1.x86_64[root@localhost ~]$ rpm -e mysql-libs-5.1.52.x86_64 --nodeps[root@localhost ~]$

3. Check whether the mysql group and user exists, if not created.

[root@localhost ~]$ cat /etc/group | grep mysqlmysql:x:490:[root@localhost ~]$ cat /etc/passwd | grep mysqlmysql:x:496:490::/home/mysql:/bin/bash

If none of the above conditions exist by default, execute the Add command:

[Root @ localhost ~] $ Groupadd mysql [root @ localhost ~] $ Useradd-r-g mysql // The useradd-r parameter indicates that the mysql user is a system user and cannot be used to log on to the system.

4. decompress the TAR package and change the group and user

[root@localhost ~]$ cd /usr/local/[root@localhost local]$ tar xvf mysql-5.7.12-linux-glibc2.5-x86_64.tar[root@localhost local]$ ls -ltotal 1306432-rwxr--r--. 1 root root  668866560 Jun  1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar-rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz-rw-r--r--. 1 7161 wheel  29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gz[root@localhost local]$ tar xvfz mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz[root@localhost local]$ mv mysql-5.7.12-linux-glibc2.5-x86_64 mysql[root@localhost local]$ ls -ltotal 1306436drwxr-xr-x. 2 root root       4096 Dec  4  2009 bindrwxr-xr-x. 2 root root       4096 Dec  4  2009 etcdrwxr-xr-x. 2 root root       4096 Dec  4  2009 gamesdrwxr-xr-x. 2 root root       4096 Dec  4  2009 includedrwxr-xr-x. 2 root root       4096 Dec  4  2009 libdrwxr-xr-x. 3 root root       4096 Dec  2 14:36 lib64drwxr-xr-x. 2 root root       4096 Dec  4  2009 libexecdrwxr-xr-x. 9 7161 wheel      4096 Mar 28 12:51 mysql-rwxr--r--. 1 root root  668866560 Jun  1 15:07 mysql-5.7.12-linux-glibc2.5-x86_64.tar-rw-r--r--. 1 7161 wheel 638960236 Mar 28 12:54 mysql-5.7.12-linux-glibc2.5-x86_64.tar.gz-rw-r--r--. 1 7161 wheel  29903372 Mar 28 12:48 mysql-test-5.7.12-linux-glibc2.5-x86_64.tar.gzdrwxr-xr-x. 2 root root       4096 Dec  4  2009 sbindrwxr-xr-x. 6 root root       4096 Dec  2 14:36 sharedrwxr-xr-x. 2 root root       4096 Dec  4  2009 src[root@localhost local]$ chown -R mysql mysql/[root@localhost local]$ chgrp -R mysql mysql/[root@localhost local]$ cd mysql/

5. Install and initialize the database

[root@localhost mysql]$ bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/2016-06-01 15:23:25 [WARNING] mysql_install_db is deprecated.

If you change the default installation path, 1)/etc/my. cnf,/etc/init. d/modify basedir = '/apps/mysql' datadir ='/apps/mysql/data' in mysqld. 2) create ln mkdir-p/usr/local/mysql/bin ln-s/apps/mysql/bin/mysqld/usr/local/mysql/bin/mysqld

[root@localhost mysql]$[root@localhost mysql]$ cp -a ./support-files/my-default.cnf /etc/my.cnf[root@localhost mysql]$ cp -a ./support-files/mysql.server  /etc/init.d/mysqld

6. initialize the password

Mysql5.7 generates an initialization password, but you do not need to log on to mysql5.7 for the first time in a previous version.

[root@localhost bin]$ cat /root/.mysql_secret # Password set for user 'root@localhost' at 2016-06-01 15:23:25 ,xxxxxR5H9[root@localhost bin]$./mysql -uroot -pEnter password: Welcome to the MySQL monitor.
